Issues:
Experimenting with time-space-taxa filtering and display using Crosstalk which enables knitting from Rmarkdown (see source) to HTML for free easy hosting on Github Pages.
Although Crosstalk synchronizes a shared data object between htmlwidgets such as the leafet map, plotly plot, and DT table, the need for aggregation across time, taxa and/or sites, necessitates migrating this type of application to Shiny for applying back-end R functions to aggregate data as interactively specified by the user.
Shiny requires a hosted solution with Shiny Server or ShinyApps.io. I’ll proceed with installing the open-source Shiny Server in the Google Cloud Platform.
